Perceptions of and Reactions to Ultra-Processed Menu Label Designs

Summary

The primary objective of this study is to explore perceptions and understanding of different menu label designs related to ultra-processed foods (UPF). Participants will be randomized to view a fast-food online menu excerpt featuring one of sixteen labeling conditions and then will answer questions about the participant's reactions to and interpretations of the label, perceived label effectiveness, the intention to purchase a menu item with the label, as well as the participant's perceptions of fast-food menu items with and without the label.
